“Diethylstilbestrol in the Prevention and Treatment of Complications of Pregnancy” (1948), by Olive Watkins Smith

“Diethylstilbestrol in the Prevention and Treatment of Complications of Pregnancy” (1948) by Olive Watkins Smith In 1948, Olive Watkins Smith published “Diethylstilbestrol in the Prevention and Treatment of Complications of Pregnancy” in the American Journal of Obstetrics and Gynecology. In 632 women treated with diethylstilbestrol, Smith demonstrated that the drug stimulated the production of progesterone, a hormone that regulates the uterine condition during pregnancy. On the basis of her article, and several follow up articles authored by Smith and her husband, George Van Siclen Smith, physicians around the world began

Gene Transfer Strategy Used to Treat Tay - Sachs Disease (2005), by Sabata Martino’s Research Group

A Direct Gene Transfer Strategy via Brain Internal Capsule Reverses the Biochemical Defect in Tay-Sachs Diseases (2005) In the early 2000s, Sabata Martino and a team of researchers in Italy and Germany showed that they could reduce the symptoms of Tay-Sachs in afflicted mice by injecting them with a virus that infected their cells with a gene they lacked. Tay-Sachs disease is a fatal degenerative disorder that occurs in infants and causes rapid motor and mental impairment, leading to death at the ages of three to five. In gene therapy, researchers insert normal genes into cells that have missing or defective genes to correct genetic disorders. The team created a virus that coded for a specific gene missing in mice with Tay-Sachs. That missing gene is called hexosaminidase subunit alpha (HEXA).

The Mustard Operation

The Mustard OperationThe Mustard Operation is a surgical technique to correct a heart condition called the transposition of the great arteries (TGA). TGA is a birth defect in which the placement of the two arteries, the pulmonary artery, which supplies deoxygenated blood to the lungs, and the aorta, which takes oxygenated blood to the body are switched. William Thornton Mustard developed the operation later named for him and in 1963 operated on an infant with TGA, and ameliorated the condition, at the Hospital for Sick Children in Toronto, Canada. Afterwards, the Mustard Operation became the primary form of corrective surgery for TGA, until the arterial switch operation largely replaced the Mustard Operation by the late 1990s.

Karl Landsteiner (1868-1943)

Karl Landsteiner (1868-1943)Karl Landsteiner studied blood types in Europe and in the United States in the late nineteenth and early twentieth centuries. Landsteiner won the Nobel Prize in Physiology or Medicine in 1930 for detailing immunological reactions in the ABO blood group system. The ABO blood group system divides human blood into one of four types based on the antibodies that are present on each cell. Landsteiner's work with blood types led physicians to safely perform blood transfusions and organ transplants. Additionally, Landsteiner researched the Rh blood factor, a protein marker on the surface of blood cells and that can impact pregnancy.

John Hunter (1728–1793)

<a href="/search?text=John%20Hunter" title="" class="lexicon-term">John Hunter</a> (1728–1793)John Hunter studied human reproductive anatomy, and in eighteenth century England, performed one of the earliest described cases of artificial insemination. Hunter dissected thousands of animals and human cadavers to study the structures and functions of organ systems. Much of his anatomical studies focused on the circulatory, digestive, and reproductive systems. He helped to describe the exchange of blood between pregnant women and their fetuses. Hunter also housed various natural collections, as well as thousands of preserved specimens from greater than thirty years of anatomy work. Hunter's work developed practices in reproductive and

“Elective Induction of Labor” (1955), by Edward Bishop

“Elective Induction of Labor” (1955), by Edward BishopIn 1955, obstetrician Edward Bishop, a physician specializing in childbirth, published the article "Elective Induction of Labor," in which he proposed the best conditions for pregnant women to elect to induce, or begin, labor. Elective induction of labor requires an obstetrician to administer a drug to help a pregnant woman to start her contractions, and to rupture the fluid-filled sac surrounding the fetus called the amniotic sac. In the early 1950s, Bishop analyzed the results of 1,000 elective inductions and discovered that some pregnant women had faster and easier deliveries with induced labor than other pregnant

Eugen Steinach (1861–1944)

Eugen Steinach (1861–1944)Eugen Steinach researched sex hormones and their effects on mammals in the late nineteenth and early twentieth centuries in Europe. He experimented on rats by removing their testicles and implanting them elsewhere in their bodies, and he found that the testes interstitial cells produce male sex hormones. He developed the Steinach Rejuvenation Procedure, which he claimed could rejuvenate men by increasing their production of sex hormones.

The Apgar Score (1953-1958)

The Apgar Score (1953-1958)In 1952 Virginia Apgar, a physician at the Sloane Women’s Hospital in New York City, New York, created the Apgar score as a method of evaluating newborn infants’ health to determine if they required medical intervention. The score included five separate categories, including heart rate, breathing rate, reaction to stimuli, muscle activity, and color. An infant received a score from zero to two in each category, and those scores added up to the infant’s total score out of ten. An infant with a score of ten was healthy, and those with low scores required medical attention at birth. Apgar originally used the score to determine how infants responded to the pain-relieving drugs given to pregnant women during labor. The Apgar score also served to determine when the infant required medical assistance, especially oxygen resuscitation. As of

Virginia Apgar (1909-1974)

Virginia Apgar (1909-1974)Virginia Apgar worked as an obstetrical anesthesiologist, administering drugs that reduce women's pain during childbirth, in the mid-twentieth century US. In 1953, Apgar created a scoring system using five easily assessable measurements, including heart rate and breathing rate, to evaluate whether or not infants would benefit from medical attention immediately after birth. Apgar's system showed that infants who were previously set aside as too sick to survive, despite low Apgar scores, could recover with immediate medical attention. Additionally, Apgar researched the effects of anesthesia used during childbirth and advocated for the prevention and management of birth defects. Apgar's work led to a decrease in infant mortality rates in the mid-twentieth century and into the twenty-first century, and
